Just give it up.
Be real with yourself.
You know, you're playing, you get that win, your entire team is in sync. It can feel great for a short while.
Maybe you decide to end it on a good note, you know, can't go to bed on a loss.
Maybe you play 1 or 2 more, maybe those could even result in a win.
But you know, deep down, be real with yourself, when you're in bed, with your head against the pillow, you know, the match making will force you towards 50%, as intended, as designed, it doesn't matter what you do or how much effort you put in. It's already decided.
Could you maybe flip the switch? Try to hard carry? Get 25 kills in a game where the rest is your team is meant to lose?
Game after game? +20lp, +20lp, +20lp?
Each game, each division, each rank.
Does that sound fun to you?
Even if you accomplish it, and hit your desired rank, diamond, masters, whatever, no one will care.
You are a nobody. No one will care.
Best you can do is show off your cool new achievement here, where you'll maybe get 2 or 3 replies.
This is your life.
